[U-Boot-Users] Trouble w/GLOBAL_DATA_PTR on PXA255

Hello Booters,

I am having some strange problems with "gd" on PXA255. Basically, I am experiencing intermittent memory corruption (e.g. a reported RAM size of 3955MB) and the like. DECLARE_GLOBAL_DATA_PTR is defined as:

#define DECLARE_GLOBAL_DATA_PTR register volatile gd_t *gd asm ("r8")

on ARM platforms. I guess the question is then - what is supposed to be in r8, and where is this supposed to be set up? It looks like the setup for "gd" is simply incorrect for my platform, but I am not sure how it supposed to be.

Please advise.

Thanks in advance, craig vanderborgh voxware incorporated
